Updating Your Scanner Drivers on Ubuntu and Derivative Distributions

We're going to do a quick demonstration on how to update SANE to the latest release. This is the underlying software and related drivers for utilizing a variety of scanners on GNU/Linux. These directions were developed and intended primarily for customers who have purchased a scanner from us that are on Ubuntu or derivative distribution/release for which does not yet include support out of the box.

As of this writing this would mean any Canon 300 or 400 series scanner. The directions are mostly applicable to users of Ubuntu 18.04, 18.10, 19.04, 19.10, Trisquel 8, Linux Mint 19, and/or any distribution based off Ubuntu 18.04, 18.10, or 19.04. Following these directions is most likely not required on distributions or releases newer than this as they will already contain a sufficently recent version of SANE (1.0.28 or newer).

Check out our video demonstration of these directions.

Open a terminal and run the following commands (Go to Activities and search for Terminal or find it via the menu system if your distribution has this):

sudo add-apt-repository ppa:rolfbensch/sane-git
sudo apt-get update

sudo apt-get install libsane sane-utils simple-scan

scanimage --version

sudo adduser `whoami` lp
sudo adduser saned lp


Before you continue make sure that your scanner is unlocked. Most if not all new scanners are locked to protect them in transit and a latch to unlock them will need to be flipped in order for scanning to work. Otherwise you will likely get confusing error messages following the steps below.

After rebooting connect your scanner and open Simple Scan (either search for it by clicking on Activities and then selecting the icon or find it through your distributions menu system).

You will need to click on the three bars (this may differ depending on the distribution and version) and go to Preferences. If everything is connected and the printer is on you should see your scanner listed under the Scanner drop down menu.

Under the quality tab you will need to set the Text & Photo Resolutions to something that your scanner supports. At the time of this writing we demonstrated scanning at a resolution of 300 dpi.

Once you have done this you can hit the Scan button to make your first scan.
